After a couple of trips to Spain in the past few years, I've become a big fan of Spanish food. I'm going to be in Manhattan at the end of May and would love to find a Spanish restaurant or tapas bar with good food and a lively atmosphere. I've been reading about several places on Chowhound and other sites, and have it narrowed down to Casa Mono, Tertulia, and Nai Tapas Bar. I've found a lot of info on the first two places, but not much on Nai. From the little I've seen, Nai is very appealing; has anyone been there?
If it helps, my favorite Spanish foods are classic things like morcilla, jamon croquettes, razor clams, boquerones, and oxtail, and the people I'll be with generally are pretty adventurous eaters.
